The Lowdown
G’day, I’m Rusty, and I’ve been watching the surf for the Jaconé area. The first few days are a bit of a dud, but there’s a golden window coming up for the experienced crew.
Sunday (6th September) is a washout. Light rain, a moderate breeze, and cross-on swell from the south at 6ft to 8ft with a short, choppy period of 7 to 8 seconds. The energy is moderate (433 to 697), but it’s all messy. More of a kiteboarding day than a surf day.
Then Monday morning (7th September) switches everything on. The wind goes glassy, and we’ve got a solid 8ft south swell with a 10-second groundswell period. The energy jumps to a strong 1370. This is heavy, powerful surf for experts only—way too big for beginners. The offshore wind cleans it up, giving you glassy, thick lines at Jaconé. The afternoon holds at 8ft with a clean cross-off breeze. Monday is the standout.
Tuesday morning (8th September) is still very good: a gentle offshore breeze, 5ft south swell, and a clean 10-second period. Energy is moderate (702). The crowds are “sometimes,” so you might have a few friends out, but it’s worth it.
The rest of the week tapers. Wednesday (9th September) starts glassy with 4ft, but the afternoon gets cross-on and small. Thursday (10th September) brings a glassy morning with 4ft and a long 12-second period—a groundswell that will wrap into the point. Water temp is about average for the season.
The second week has a gap on Saturday (13th September) with strong onshore winds and tiny, weak swell (energy down to 111). That’s a blank day. Monday (14th September) morning bounces back: glassy, 5ft south swell, 12-second period, and moderate energy (877). A solid morning. Thursday (17th September) morning is another gem: glassy, 5ft, 10-second period, and 594 energy. Clean and fun.
The absolute best of the forecast? Monday (7th September) at Jaconé. Big south swell, glassy wind, strong energy, and a proper challenge for those who can handle it. Be there.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
